skyfox60 works with 2s up to 6s

skyfox60 Your board should support this sensor. It is connected via the I2C - Bus. ( SDA ( DA ) and SCL ( CL ) as well as +5V and gnd from the board. Refer to your boards describtion and to your used software. On MATEK F411 or F405 and those, and with INAV software, it works perfect. Well, on INAV it only has a indicating function as of now. The values measured will be indicated in the OSD, but not taken into consideration for navigation or other purposes. Hopefully that changes by some time.

skyfox60 Even in a ( felt ) calm position you will not achieve an constant zero indication. There is allways a little bit indicaated around zero. These pressure sensors are very sensitive and on low speeds ( which is around zero ) it is nearly impossible to get a stabler and correct indication. This failure becomes lower and lower at more and more raising speeds. So dont worry about that. Just fly and check the speeds indicated. On a really calm day ( very early or later in the early evening, your indicated airspeed and your GPS ground speed should more or less match. With talwind flying your GPS speed ( Ground speed is the higher one, and with headwind, your indicated airspeed is the higher one. Make sure to determine your stall speed, too. That is only dependent on and related to the airspeed, and not on the Ground ( GPS ) speed. You will see, the 4525 works perfectly, once your aircraft has resonable speed achieved.

skyfox60 Can you provide a foto of how you did it, thx

skyfox60 Well, with 2 cloverleaf-antennas I got 1.2 to 1.5KM which is around a mile, a bit pending on the situation. It depends more on the sensivity of your receiver aund on the quality of your antennas. With directional ( beam- ) antenna, you can go far more, but the antenna has to look towards the sender. ( antennatracker b.E. ). With the shown antenna instead, you will not reach that great distances. The cloverleafs are far better, so buy some.

skyfox60 the amperage only states the time the battery lasts. So b.E. if 1100mAh lasts for one hour, a 2200mAh will last 2 hours. The max. Voltage is the thing to be not not exceeded.

skyfox60 overall, yes, if your receiver has SBUS output. B.E. FrSky S'BUS receiver in D 16 modes or Radiomaster-receivers such as R168 or R161 delivers 16-ch S-BUS, making you able to use all 16 channels for servos, ESC+s or whatever. So, it mainly depends on your receiver, not on your transmitter.
